Presented in a high-quality filter box
Quickly capture dark frames to optimize photo quality
Opaque - blocks all light from the imaging camera sensor. Help remove dark currents - essential for astrophotography
Easily eliminate camera noise and hot pixels
Dark frame acquisition helps remedy such noise and "hot pixels" by canceling out these disruptive effects during image processing
Threaded and can be directly connected to your filter wheelfor fast conversion between different filters;
Made of metal for durability. High quality packing box includes foam-lined plastic case
Strong, steady and easy to setup absolutely worth the price.
Low guiding error even at near payload capacity (4.5kg).
Easy polar alignment using fine adjustment knobs.
Low payload capacity suitable with small refractors best for traveling. With payload near capacity, weight management is essential because the counterweights included almost can not balance the kit.
